A glass surface is provided with a scratch-resistant, lubricous, substantially transparent and colorless coating by applying to the hot glass surface an aqueous composition comprising polyethylene and a silane having, attached to the silicon atom, three hydrolyzable radicals of the class consisting of methoxy, ethoxy and chloro, and one alkyl or acyl radical having from 12 to 18 carbon atoms.
Articles having a scrub resistant, water repellant and dirt resistant vitreous surface are provided by (a) heating the article to a surface temperature above 400.degree.C, until the surface becomes free of water; (b) adjusting the surface temperature to between 310.degree. and 370.degree.C. and applying a siliconizing medium comprising an organosiloxane; and (c) allowing the article to cool to ambient temperature.
A method for silicone treating glass header capacitors to reduce surface current leakage in high humidity environments without adversely affecting the capacitor's normal physical and electrical characteristics. The silicone is an alkyl-alkoxysilane applied to the glass header without formation of metal corrosive by-products and without the need for damaging high temperature curing. The treated capacitors exhibit little increased current leakage in environments of 100% relative humidity compared to 30% relative humidity.
Coated glass containers having a surface cured composition which is the reaction product of at least one ethylenically unsaturated monoene, a polyene and a curing initiator. The coating is bonded to the exterior or interior surface of a glass container to increase hardness and strength.
A glass article, especially of hollow glass, carries a coating resulting from the deposition, in one or two stages, onto the surface of the glass, of at least one monoaminosilane and of at least one lubricating substance such as an optionally oxidized or partially oxidized polyolefin. The coating provides desirable properties of wet and dry abrasion resistance (scratch resistance), substantial invisibility, and adhesiveness for labels. Articles having labels directly attached to said coating are also provided as well as the process for obtaining the desired properties.
An improved process for making a multiple pane fire resistant window whose spacings are filled with an aqueous gel possessing multiple carbon bonds, wherein the improvement comprises placing a thin layer of an adherence agent on the contact surface of the panes, prior to placing the aqueous gel in the spacing. The adherence gel is selected from the group consisting essentially of organic titanates, organic zirconates, and silanes able to react with the aqueous gel's multiple carbon bonds.
